Original GitHub issue: https://github.com/netbirdio/netbird/issues/2953

After upgrading from version 0.32.0 to 0.33.0, we see random network disruptions although netbird status is reporting no disconnects. This issue happens several times per hour even if the nodes sit on the same LAN. Eventually, we've downgraded to 0.32.0.

To reproduce: Install a larger bunch of Linux nodes on the same LAN, put some serious workload on them and watch random network errors without being reported by netbird status. In our case, we run Longhorn on the nodes and everytime this happens almost all of the volumes degrade, causing huge network activity in order to rebuild new volume replicas on other nodes.
